Very good point, Tom. This requires a minuscule change in the load-C setting
compared to a larger inductance. I hadn't thought much about this component
before -- "everybody knows" you use a couple mH here. Why do all the amp
designs in my handbooks (ARRL & Orr) call for 1 mH or more?

Why don't we see problems with series resonances in this part when >1 mH is
used?
